to variations in the consistency ol' the stock a hh'h atlect itsfluidity.

ltel'erringg; to the drawings wherein the inveution is shown in,pret'erred form, t, is the pulp-hex divided by partitions, 2 and 23,into three compartments, one of which is a pull receiver, t, suppliedthrough a hottom'inlet, a, with pulp from a pump, 3.3T.

A weir is formed at, (S, in the partition, 2, over which the surplusstock [lows into the waste-ctunpaitment, 7, from which it. es apes throuh an outlet. :58, and is returned to the pulp-chest from which the pumpderives its supply, said pulpwhest heinoomitted from the drawings, asthe same forms no part of, the n'esent inventionv The stock which is tohe delivered to the papeumaliing machine, is permitted to How out fromthe pulpreceiver, 4, through an outlet, 38, near the hottom thereof intothe compartment, 9, from which the stock llowsthrough an outlet, it), tothe paper-nothing machine, not shown.

l have shown the outlet, 38, provided with a slide- 'alve or gate, 11,adapted to he 0perated hy a hand-lever, t2, whcrehy the sup pl v to thepaper-making machine am he to some extent controlled; and also providedwith an oscillating valve, 13, whereby, by 11: :ans of my invention,said supply of stock to the paperumiliing machine can he reg'le latcdand controlled with substantial accuracy to secure a uniform supply ofpulpliher to the piuieranalting machine under different conditions (it(:onliisteuc)"oli the pulp or stock.

it is well umlerstood in the art that pulp tor the manuhu-ture oi papervaries more or less in consistency, and hence tiuidity, and as the wateris permitted to escape from the pulp in making the paper which is formedfrom the tihcr of the pulp, it is-uccessary in order to secure paper ofunil'orm weight or thicl-cncss that the supply to the paper-maltingmachine should he substantially uniterm in the quantity of ])Hl])*lllttlcarried It thus lmconurs necessary to supply to the paper-making machinea ,e'reater quantity of thin pulp than ot' thick pulp in a giventhickness or weight of paper.

it has heen atlenu'itcd to utilize changes in the level of pulp in thepulp-rta'ei\'er to auto matically operate a 'alve controlling; theoutflow to the paper-makingmachine, so that any considerable rise in thelevel at the stock causes a partial operation of the valve, 13, which Iam able to do by employing meeha nlsln which is not only responsive tothev more considerable variations in level due to vvariations in thefluidity-of the pulp, but

is also responsive to the lesser variations in leveldue to the mlsationsot' the supply.-

pump, while at the same time a constant vibrating. movement is impartedto the out let valve which prevents clogging of the outlet-opening andassists the outllow ol the pulp 't'herethrou 'h.

As a means for acconmllsluug the object pot the present invention, lhave shown the valve, 13, eonnecttal by an operating-link, 15, with onet'ndsof a lever, l6, pivoted or fulcrumed at, 17, upon a cross baig-lS,extending across the top of the pulp-box, the other end of said loverbeing connected by a link, it), with a float adapted to ride upon thetop of the liquid-pulp in the pulp-receiver, 4. The connections thusestablished between the float, 20', and valve, 13, are positive in theiraction so that each vertical movement of the float, 20, isimmediately.transmitted to the valve, 13. The float, 20, is constantlyrising and falling in response to the pulsations of the puinp-s -lpply,and this rising and falling of the float is transmitted to the valve,13, in the form of-a vibrating movement causing said valve to constantlyoscillate or vibrate hack and forth, thus agitating the stock in theimmediate vicinity of the valve and preventing, the same from cloggingthe outlet opening.

\Vhenever the proportion of fiber in the stock is materially increased,the stock will by reason of its less fluidity rise to a higher levelcausing the float, 20, to be correspondinglyiraised and the valve, 1?),to be correever degree the valve, 13,'is ctfecti'vely open, 0

spondingly partly closed; and on the other hand, when the pulp containsless fiber, it will flow more freely over the weir, 6, thus lower- 5ing' the level of thecstock, permitting the float to descend and therebyimpart to the valve, 13, a corresponding opening-movement. It will beunderstood that to whatits constant oscillating or vibrati 'ig movementcontinues, due to the pump-pulsations.

The link, it), reciprocates through a guide,

2l,swivcled at, 22, upon the cross-bar, 13.

Each of the links, 15 and 19, is pivotally 6 and adjustably mounted uponthe lever, 16., by means of a block, 23, swiveled upon the lever, 16,through which block the link passes, said .block being eontined betweentwo nuts, 24 and 253, screwed upon the link \vlicreby verticaladjustment of the link can be accomplished. Longitl-ldinal adjustment ofthe lever, 16, by which the leverage can be varied as desired to meetdifferent con ditions in use, is provided for by means of alu[cram-block, 26, through which the lever is adapted to slide, and an:nljusting-screw,

27, which passes through a nut, 28, on the l'ulcrumblock and isrotatively mounted at, 2!), and 30, upon the lever. v

Nodctailed showing of the pun1p, l7, had been made as any of the knowntypes of pulpfeeding pump may be employed.

What l claim as new and desire to secure by Letters Patent is i In apaper making machine, a pulp loos; ha ring an outlet; a valvecontrolling vthe outlet; a float; 'a levcr; connections uniting the endsof the lever with the valve and with the float; a pivotally mountedfulcrum block so in which the lever is slidable, the lever having a pairof lugs located u JOn opposite sin 5 of the block and between tieconnections, screw threaded into the block and marsh in the lugs, thescrew extending upturn. sides of the block and constituting a tru forthe lever; and nuts threaded upon. .7

' screw and adapted to engage the lugs.

In testimony whereof, I have hereunto set my hand this 24th day of June,1911.
